AbstractBased on the previously-reported porosity multilayer technique, cold electron emission properties of porous silicon (PS) electroluminescent diodes with a structure of Au/PS/n-type Si are further improved by introducing a graded-band multilayer structure. It is shown that electrons are quasiballisticly emitted from PS diodes owing to a significantly reduced electron scattering in PS layer. As a result, the emission current shows a fluctuation-free behavior. These observations are very important for both understanding the electron transport in PS and developing high performance electron emitters in application to vacuum microelectronic technology.

In this work, different from the typical gas sensors responding by gas adsorption on their surface, a new gas sensor using carbon nanotubes (CNTs) as electron emitters is introduced for detecting inert gases which hardly possess chemical or electrical adsorption in normal conditions. The proposed sensor works by figuring out the variation of the dark current and the initial breakdown voltage on Paschen's law under applied high voltage. As they depend on the gas composition and the pressure in a sealed chamber, it is possible to detect the identity and the concentration of unknown inert gas species.
